Complete Kamstrup energy meter set: MULTICAL 603 calculator (cooling configuration E3), flanged ULTRAFLOW ultrasonic flow sensor and Pt500 sensor pair — manufactured 2024, new in Barmaan stock, EN 1434 + MID approved. The photos show the actual set in our warehouse.
The Kamstrup MULTICAL 603 thermal energy meter is the gold standard for heating and cooling energy measurement in Europe. The set offered here is a complete, factory-matched assembly: a MULTICAL 603 calculator (type 603E519), an ULTRAFLOW ultrasonic flow sensor with a flanged body in cast stainless steel 1.4308, and a pair of Pt500 temperature sensors. Built in 2024, entirely new and held physically in Barmaan's warehouse; every photograph on this page is of this very set, and the calculator label and the temperature sensors carrying the matching serial are legible in the images.
This unit is configured at the factory as a cooling meter (class E3, approval TS 27.02 012): cooling energy is computed from the product of the flow passing through (measured ultrasonically) and the difference between the flow and return temperatures (the Pt500 pair), and is displayed at 8-digit resolution in MWh. The calculator's temperature range is 2 to 180 °C and its temperature-difference range is 3 to 178 K.
Flow is measured on the ultrasonic transit-time principle with no moving parts whatsoever — no wear or loss of performance over its life, with low pressure drop and long-term stability. Per EN 1434 the flow sensor accuracy is ±(2 + 0.02qp/q)% (capped at ±5%) and the calculator accuracy is ±(0.5 + ΔΘmin/ΔΘ)%. Per the device label the configured size (qp) is shown on the display, and Barmaan's engineers read it off and confirm it before sale.
The MULTICAL 603 is approved to EN 1434:2015 and to the European MID directive (2014/32/EU) and may be used for legal metrology and energy billing. This unit is powered by a D-cell lithium battery with a lifetime of up to 16 years; a programmable data logger (down to minute logs), a 2-second integration interval and two communication module slots (M-Bus, wireless M-Bus, Modbus, BACnet, LoRa and others) allow connection to BMS systems and remote reading. The set's temperature sensors are Pt500 types to EN 60751, 5.8 mm in diameter and rated IP68.
This set is a dependable choice for chiller plants, district cooling and heating, towers and commercial complexes, hospitals, and anywhere accurate and legally valid thermal energy measurement is required.
Barmaan supplies industrial instrumentation; this item is offered with a guarantee of authenticity, the option to inspect it in person at the warehouse, selection consultancy, and installation and commissioning support. To obtain pricing, submit a proforma invoice request from this page.

The set comprises three components: a MULTICAL 603 calculator (type 603E519), an ULTRAFLOW ultrasonic flow sensor with a flanged body in cast stainless steel, and a pair of Pt500 temperature sensors (type TemperatureSensor 63). The temperature sensors and the calculator carry matching serial numbers — that is, the set was matched and approved together at the factory. The photographs on this page were taken of this very set in Barmaan's warehouse.
Per the factory label, this unit is configured and approved as a cooling meter (energy class E3, approval TS 27.02 012) — suited to chillers and district cooling. The MULTICAL 603 platform generally supports heating, cooling and combined operation; if your project requires a heating meter, Barmaan's engineers will advise on the possibility of supplying the appropriate configuration.
Per the calculator label, the qp and pfi values are shown on the device's display ("qp, pfi: See display"). The flow sensor body is flanged and made of cast stainless steel 1.4308. Before issuing a proforma invoice, Barmaan's engineers will read the exact size (DN and qp) off this device's own display and confirm it to you, so that it can be matched to your project's requirement.
Yes. The MULTICAL 603 is approved to EN 1434:2015 and to the European Measuring Instruments Directive (MID 2014/32/EU) and may be used as a legal thermal energy meter. Per EN 1434 the calculator accuracy is ±(0.5 + ΔΘmin/ΔΘ)% and the ultrasonic flow sensor accuracy is ±(2 + 0.02qp/q)% (capped at ±5%).
The MULTICAL 603 has two communication module slots, and modules are available for wired M-Bus, wireless M-Bus, Modbus, BACnet MS/TP, LoRa and others. The data includes energy, flow, power, flow and return temperatures, and history logs. The internal data logger is programmable down to minute resolution.
You can submit a proforma invoice request from this page; Barmaan's engineers will confirm the price and delivery terms within one working day at most. The item is in stock, so once the order is confirmed it is ready for collection or shipment with no overseas procurement lead time. Authenticity is guaranteed, and you are welcome to inspect the device in person at the warehouse.
